APPARATUS FOR PU RIFYING VAPORS.

SPECIFICATION forming part of Letters Patent K014325253, dated Jilly 22, 1890.

Application filed February ll. 1887. Serial No. 227,341. (No model.)

To all whom it may concern.-

Be it known that I, HENRY GoLDWA'rER, of the city and county of New York, in the State of New York, have invented a certain new and useful Improvement in Apparatus for Purifying Vapors, of which the following is aspecification.

My invention isintended more particularly for refining petroleum; but it may be used with advantage'in the treatment of other material in avaporous condition or for the purifying of permanent gases.

I provide a tight chamber with a perforated base and with a provision for leading the vapor or gas in at the bottom and taking it away at the top. One side of the chamber opens after the manner of a door and affords free access to the interior, in which I place a series of removable pans, each perforated and containing a layer of charcoal or other-purifying material.

ln'what'l esteem the best means of carrying out the invention the chamber is cylindrical and the pans circular, but of less diameter. A series of large apertures are arranged in the annular space between, extending about half-way around on the side opposite the door. A semi-cylindrical partition extends up between this annularspace and the central space. In thrusting in the pans this partition serves as a gage to indicate when they are correctly placed. This semicircular partition is also useful to some extent in defending the back edges of the pans against the absorption of the vapors which rise up in the annular space.

The accompanying drawings form a part of this specification.

Figure 1 is a central vertical section showing the novel portions, with so much of the other parts as is necessary to understand their relation thereto. This figure shows the pans in place. Fig. 2 is a horizontal section on the line as w in Fig. 1 with the pans removed. The turning plate has been adjusted to compel the vapors to ascend through the pans. Fig.3 is a corresponding horizontal section, but with the turning plate shifted to let the vapors go idly past. Figs. 4 and 5 are on a larger scale. Fig. 4 is a plan view, and Fig. 5 is. a central vertical section, of one of the pans.

Similar letters of reference indicate correin the molds.

spending parts in all the figures where they occur.

A is a retort, and B is a series of separati- .ing devices adapted to arrest the dense liquid and return it to the retort, allowing only the dry vapor to pass through the neck Ointo the base of a cylindrical chamber D. To the top of this chamber is connected a pipe E, leading to a condenser or series of condensers. (Not shown.)

D is a perforated false bottom of the chamber D. There are two sets of perforations. One set near the center are marked (1. Another set near the periphery are larger and are marked (1. D is a partition extending halfway around on'the interior and joined tightly to the casing or exterior of D at its ends.

Under the perforated plate or false bottom gDu's partiallyl-rerolving plate M, turning on a central pivot m, having perforations adapted to register with those in the false bottom, and provided with a handle M, which moves in a slotin the true base of the chamher, the slot being covered by a plate M", which slides with it as the plate M is partially revolved one way or the other by the handle M.

I employ circular pans G, adapted to match tightly by their rims one upon another and to be introduced and removed through the side of the'chamber'D on opening the door D*. These pans are made of carbon-one-third (t) coke, one-third (4;) wood-charcoal, and onethird cannel-coal. These three materials pulverized and intimately mixed are molded into shape under moderate pressure. I have in my experiments burned or baked the pans I believe it is practicable to do so on a large scale; but this may be varied. The pans are liberally perforated with small holes. These small holes may be made in the molding or by drilling or otherwise afterward. The top and bottom faces of the rims of the pans should be ground or otherwise finished Very truly, so that the pans on being rested upon each other will make tolerably tight joints.

H is a layer of fin sly-broken ch arcoal or other purifying material laid on the several pans. When the door D* is open, the pans may be removed and new ones introduced, either singly or in a mass, and the door closed and secured.

The pans G, by being made of the material and in the inanner specified, serve themselves very efficiently to purify the vapors or gases.

It is important that these extremely volatile naphthas, or whatever they may be called, shall not be passed through the charcoal. Their contact with the charcoal andtheir saturation thereof injuriously affect the subsequent action by causingthe charcoal to give out small quantities of thevolatile matter, which, min-- gling with the less volatileparts afterward treated,induces mischief. In commencing the treatment therefor the perforated plate M is turned into the position toclose the passages (l and open the liberal passages d, as shown in Fig. 3. Thus conditioned the light vapors pass up through the liberal passage (1' and through the semi-annular space between the interior of the casing D and the semi-cylind rical partition D They are shielded by the partition D from-contact with the edges of the pans. They are not absorbed by the pans or the St-lfllilllILOf' purifying material lying thereon, but pass away to the condenser unaffected. When the proper period arrives,

the attendant shifts the plate M so as to close, the apertures d and open the apertures d.

This condition is shown in Fig. 2. Now the vapors cannot pass up outside, but are compe'lled .to rise through the perforations in the \Vhen a charge of petroleum or other maseveral pans and through the interstices in the purifying material H lying thereon. The

purifyingis effected in the well-known manner.

In operating in a large way I propose to pass the vapors through severalchambers D, all

provided with the pans and appurtenances, substantially as described, the contents ofthe first chamber being already partially saturated and the last one beingfresh. This economical mode of utilizing the purifying elfect of' a given amount of material 1S familiar in many branchesiof the art and need not be further described.

Other modifications may departing from the principle or sacrificing the advantages of the invention. p

I can use perforated pans of sheet metal in place of the carbon pans G. v

The apparatus may be used with some advantage in treating permanent gases. I am aware that many efforts have been madeto filter vapors through charcoal and be made without analogouspurifyi-ngagents. Such, broadly, I,

do not claim; but,

Having now fully described my invention, 70

what I claim as new, and Letters Patent, is-

In an apparatus for purifying vapors, a retort and suitable passages, in combination with the casing D and a series of removable pans G, arranged so that a portion of an annular passage is provided between such series desire to secure by and the casing, and with the perforated floor D and movable perforated plate M, arranged for joint operation as herein specified.

=In testimony whereof I have hereunto set my hand, at New York city, this 7th day of February, 1887, in the presence of two subscribing witnesses.
